Abstract: A system for detecting proximity between a first transceiver and a second transceiver. Each of the first and the second transceivers includes at least one primary and secondary radio module. The primary radio module of the first transceiver is able to communicate with the primary radio module of the second transceiver, and the secondary radio module of the first transceiver is able to communicate with the secondary radio module of the second transceiver. The first and the second transceivers are configured to estimate a primary communication distance between the primary radio module of the first transceiver and the primary radio module of the second transceiver, and estimate a secondary communication distance between the secondary radio module of the first transceiver and the secondary radio module of the second transceiver.

Abstract: An electronic system for a battery designed to supply electrical power to an application, such as in an aircraft, that includes a main power supply, comprises a charging circuit (30) with a charger (K3C), a first battery discharging circuit (20) in parallel with the charging circuit, a component ensuring continuity of discharge (D3) and an electronic control unit adapted to control opening and closing of the discharge switch (K2) and adapted to control said charger (K3C). The control unit keeps the battery charged as long as it is not being called on to discharge and interrupts battery charging and sets the discharge switch (K2) to the closed position when a call for power is detected from the application, the component ensuring continuity of discharge (D3) allowing passage of a discharge current during a transitional phase of closing of the discharge switch (K2).

Abstract: An electronic system for a battery comprises a charging circuit (20) for the battery connected to a connector powering the charging circuit (15), a control and monitoring circuit (30) for the operation of the battery, and a discharge circuit connected to power connectors (2) of the battery. The control and monitoring circuit (30) interrupts battery charging when there is a call for current via the power connectors (2) of the battery. The electronic system has application to rechargeable batteries used to provide back up power.
